Feat scale point cloud with users information

[danielsanjosepro]

Description

Closes #10

• [x] Function to get scaling of the point cloud from ceiling and floor planes
• [x] Test case functions for it (we can remove this, not really needed)
• [x] Function to get scaling from 2 pairs of points of two images and its distance
• [x] Test this function.

Try it yourself

• Try the scaling function with test_scaling_from_room_height.m (not tested with actual ceiling and floor planes, only dummy examples)
• Try running 3D reconstruction test_multiview.m in the delivery area then run test_scaling_from_two_points.m. In the test script 2 points of the door are marked and the point cloud is scaled based on its height.

For now, assuming that the door in delivery area is 2.1 m high:

I get this (left unscaled with blue points for the door, right scaled):

Looks good.

This is ready. One thing: should I move the test scripts somewhere else, or is it fine like this for now?

Maybe we could assume some default value (still allow setting it in some gui menu) for the room height, there has to be some DIN norm for living spaces and industry (2.4m for living according to BayBO). This would allow us to reduce user interaction and remove complexity.

I would add something like that in the gui

I think the review is enough: merging.
